Direct answer

Weekly rent is annualized over 365 days and divided by 12 so the monthly result matches a calendar-month budget.

PCM = weekly rent x 365 / 7 / 12

How this calculator works

PCM = weekly rent x 365 / 7 / 12. Weekly rent is annualized over 365 days and divided by 12 so the monthly result matches a calendar-month budget. The result keeps the period math consistent, so a weekly, 14-day, 28-day, monthly, or annual amount can be compared on the same basis.

When to use this page

Use this when a UK-style listing uses PW, PCM, or 4-weekly wording and you need one clear monthly or weekly comparison.

What this result does not include

The result converts rent only. Utilities, deposits, parking, pet rent, service charges, insurance, move-in fees, proration, and lease-specific payment rules are not included unless you add them to the rent amount yourself.

How to read the comparison

Use the converted amount for the budget period you actually plan with, then keep the original listing period visible so you do not lose track of how rent is collected. A calendar-month result is best for monthly bills, while a weekly, fortnightly, or 4-week result is better for matching a payment cycle.

PW, PCM, and four-week rent

PW means per week and PCM means per calendar month. Multiplying weekly rent by 4 gives a 28-day amount, not a calendar-month amount. This calculator annualizes PW rent, then divides by 12.

Scope of the result

GBP is available in the currency selector. The result is rent arithmetic only and does not determine lease terms, included costs, fees, or legal obligations.

Worked examples

GBP 190 PW example

GBP 190 per week is about GBP 825.60 PCM using 190 x 365 / 7 / 12. Multiplying by 4 gives only GBP 760 for 28 days.

Calculations use a 365-day year, 7-day weeks, 14-day fortnightly or biweekly periods, 28-day four-week periods, and 365 divided by 12 days for a calendar month.
